I made a cranberry,raspberry,ginger & a cartain of purple grape juice wine on the 3rd of november with 1000g of brown sugar, 2 camden tab & 1 tsp nutriant. start SG was 1130 6th nov i put tank heater in as it did not want to ferment then she started on the 25th december it was down to 1000 then on the 3rd jan she was still down to SG 1000 & has stayed there, so was going to bottle but there is a sour taste so much so that you could not drink it. what shall i do with it or can i salvage it.
